Marine Bio Day 2

Which of the following is a noticeable effect of climate change?

• Decrease in ocean salinity

• Melting of polar ice caps

• Increase in volcanic eruptions

• Decrease in animal migration

Which regions are predicted to experience the most warming due to climate change?

• Southern Africa and Australia

• Alaska, Russia, and Nordic countries

• South America and Southeast Asia

• Central Europe and the Mediterranean

Why might increased snowfall over Greenland and Antarctica offset rising sea levels from other causes?

• Snowfall increases ocean evaporation

• Snowfall adds more water to the ocean

• Snowfall keeps more water stored as ice

• Snowfall raises global temperatures

Explain how long-term sea level records can help scientists understand the impact of climate change.

• They show only short-term weather patterns.

• They provide data on local animal populations.

• They record changes in climate, oceanic systems, and glacial coverage over time.

• They predict volcanic eruptions.

A healthy ocean is described as one where marine, coastal, and estuarine ecosystems are functioning well. Which of the following is NOT a component of a healthy ocean?

• Diverse plant and animal communities

• Balanced physical, chemical, and biological processes

• High levels of pollution

• Functioning watersheds that drain into the ocean

According to the Final Action Plan for the West Coast Governors' Agreement on Ocean Health, what is a likely consequence of improperly balanced human activities on ocean ecosystems?

• Ocean ecosystems will remain unaffected.

• Ocean ecosystems will almost certainly be affected negatively.

• Ocean ecosystems will become more productive.

• Ocean ecosystems will recover quickly.

Which of the following is defined by the U.S. Environmental Protection Agency as a point source of pollution?

• Rainwater runoff from streets

• A pipe discharging pollutants from a factory

• Fertilizer spread on farmland

• Litter on a beach

What is the main difference between a combined sewer system and a separated sewer system?

• Combined sewer systems only handle rainwater.

• Separated sewer systems mix stormwater and sewage.

• Combined sewer systems mix stormwater and sewage, while separated systems keep them apart.

• Separated sewer systems discharge directly into oceans.

Explain how changes in ocean currents, upwelling, and productivity can be linked to human activities and climate change.

• These changes are only caused by natural events.

• Human activities and climate change can stress ocean ecosystems, leading to changes in currents, upwelling, and productivity.

• Ocean currents are not affected by human activities.

• Productivity in oceans is unrelated to climate change.

A city with an old combined sewer system experiences heavy rainfall. What is a likely environmental consequence based on the information provided?

• All water is treated before being released.

• Only stormwater is released untreated.

• Combined runoff and raw sewage may overflow and discharge directly into a nearby body of water.

• No pollutants enter the water system.
